MAX202ESE+T

Analog Devices Inc Maxim Integrated · RS232 ICs · SO-16

MAX202ESE+T from Analog Devices Inc Maxim Integrated, in a SO-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive terminal of the 0.1µF flying capacitor C1 used by the +5V-to-+10V voltage doubler.
2 V+ power_out Charge-pump output that stores approximately +10V on the V+ filter capacitor, and a small amount of power may be drawn from it at the cost of reduced noise margin.
3 C1- passive Negative terminal of the 0.1µF flying capacitor C1 used by the voltage doubler.
4 C2+ passive Positive terminal of the 0.1µF flying capacitor C2 used by the +10V-to-−10V voltage inverter.
5 C2- passive Negative terminal of the 0.1µF flying capacitor C2 used by the voltage inverter.
6 V- power_out Charge-pump output that stores approximately −10V on the V- filter capacitor, and a small amount of power may be drawn from it at the cost of reduced noise margin.
7 T2OUT output RS-232 driver 2 output that swings ±5V minimum into a 3kΩ load per EIA/TIA-232E, with ±60mA typical short-circuit current and continuous short-circuit duration allowed.
8 R2IN input RS-232 receiver 2 input with about 5kΩ input resistance to ground, rated for ±30V input voltage and +0.8V/+2.4V thresholds.
9 R2OUT output CMOS receiver 2 output that is inverting relative to R2IN, and sits at logic 1 when the input is shorted to ground or left open.
10 T2IN input TTL/CMOS driver 2 input with an internal 400kΩ pullup to VCC, so unused inputs can be left open and should be driven high or open in shutdown to minimize supply current.
11 T1IN input TTL/CMOS driver 1 input with an internal 400kΩ pullup to VCC, so unused inputs can be left open and should be driven high or open in shutdown to minimize supply current.
12 R1OUT output CMOS receiver 1 output that is inverting relative to R1IN.
13 R1IN input RS-232 receiver 1 input with about 5kΩ input resistance to ground, rated for ±30V input voltage and +0.8V/+2.4V thresholds.
14 T1OUT output RS-232 driver 1 output that swings ±5V minimum into a 3kΩ load per EIA/TIA-232E, with ±60mA typical short-circuit current and continuous short-circuit duration allowed.
15 GND power_in Ground reference for the device and the RS-232 signal levels.
16 VCC power_in +5V supply input, specified at VCC = +5V ±10% for the MAX202.
